To all whom it may concern: I

Be it known that I, W'ILLIAM MUIR, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Siphon-Valve, of which the follow-.

ing is a full, clear, and exact description.

Among the principal objects which the present invention has in view are: to provide means for inaugurating the flow in a siphon in a flushing tank employing a siphon; to provide means for avoiding leakage in flushing tanks by perforating the lining thereof; and to provide an actuating mechanism easily operated and one that is durable and requires little attention after installation. 3* r Drawings-Figure 1 is a vertical cross section of a fragment of a flushing tank and a siphon head with which a flushing pipe is provided, the section being taken as on the line 11 in Fig. 2; Fig. 2 is a longitudinal section of the same, the section being taken as on the line 2-2 in Fig. 1; Fig. 3 is a detail view of a plunger head employed in connection with the present invention; Fig. 4 is a detail view of a loose piston head employed for elevating the water in the siphon head.

Descriptz'0n.-As seen in the drawings, a tank 9 is normally supplied with water 10 at an established level, such as indicated in Figs. 1 and 2 of the drawings. Any suitable and conventional means for supplying the water to the tank and maintaining the level of the same therein, may be employed. The tank 9 has fixedly mounted therein a gooseneck pipe 11, which has an end threaded extension, the threads whereof are engaged by a locking nut 12, which permits a union for the gooseneck pipe 11, with the flushing tank of the system in which it is employed.

Depending from the short end of the pipe 11, is an inverted cylinder 13, the open lower end of which is disposed adjacent the bottom 14 of the tank, and establishes the lower water level therein. Vater flows freely into the cylinder 13, to the high water .level in the tank, and is held normally therein. In entering the cylinder 13, the water displaces the piston head 15, which normally rests in the plunger 16. The cylinder 13 is provided with open-ended guide tubes 17 which tubes extendthrough guide collars 18 on the plunger 16. The collars 18 are tapered at their upper ends to serve as registering members to adjust the openings 19 in the disk 15, the said openings loosely fitting the collars 18 when normally disposed. The collars 18 extend above the disk 15 when assembled, and serve as stops for the lift of the plunger 16 when elevated by the The chains 20 are spread as shown best in Fig. 1, and are connected at their upper ends by a cross bar 21, and at their lower ends by a spreader bar 22. The cross bar 21 is suitably connected with a rocking lever 23 of conventional arrangement and construction.

and operated according to the usual-practice. The spreader bar 22 is connected with and forms one of the median pivots of a lazy tongs 2 1. The lazy tongs 24 is'pivotally attached by a bolt 25 with the bottom 14, and by a bolt 26 with lugs 27 dependent from and disposed adjacent to the center of the plunger 16, as shown best in Fig. 1 of the drawings.

From the foregoing it is obvious that if the lever 23 is operated to lift the end thereof connected with the cross bar 21, the chains 20 are drawn up through the tubes 17, and the lazy tongs 21 is extended tolift the plunger 16 upward through the cylinder 13, until arrested by the collars 18 engaging the top of the saidv cylinder. It is equally obvious that when the lever 23 is returned to its normal position, the weight of the plunger 16 and parts connected therewith causes the lazy tongs 24 to collapse, the parts returning to their normal positions as shown in the drawings.

Operation.-lVhen the parts are disposed as shown in the drawings, the water in the cylinder 13 is at the normal level and the disk 15 has been permitted to settle on the plunger 16 where'it closes the elongated passages 28 formed in the said plunger. lVhen the lever 23 is rocked, thespreader 22 is elevated, and the lazy tongs 241 connected with said spreader is rapidly extended to lift the plunger 16 and disk .15 supported on the same upward through the cylinder 13. The water above the disk 15 is elevated thereby upward through the short extension of the gooseneck pipe 11 to fill said pipe. Then the upward movement of the plunger 16 is arrested by the collars 18 engaging the top of the cylinder 13, the established flow of the water upward through the cylinder 13, lifts the disk 15 from the openings 28, and

mately that of the lower edge of the cylinder 13, when air entering the cylinder 13 and the gooseneck 11 operates to break the siphon es- It is obvious that the collapsing operation of the lazy tongs 24 and the lowering of the plunger 16 to its normal position, does not of necessity wait on the completion of the "operation of the siphon and of the delivery of the water from the tank 9 as above described.

The flow through the cylinder 13 is not sufficient to maintain or float the plunger 10 -and parts connected therewith.

ger 16. When, however, the flow of the Water has been suspended due to the break ing of the siphon, the disk 15 is permitted to settle upon the plunger 16, the tapered ends of the collars 18 operating to guide the disk 15 to its normal position.

Claim:

A siphon, the short leg of which comprises an open-ended inverted receptacle; a plunger reciprocatively mounted therein, said plunger having open passages therethrough; means for closing said passages when said plunger is moved toward the delivery end of said receptacle; and means for lifting said plunger, said means embodying Witnesses:
